With respect to magnetic properties, the most interesting phenomena are usually observed for combination of 3\(d\)  with 4\(d\) /5\(d\)  TM ions at \(B\)  and \(B’\)  sites, leading for instance to high temperature (\(T\) ) ferrimagnetism in Sr\(_2\) CrOsO\(_6\)  [1]}, half-metallic behavior in Sr\(_2\) FeMoO\(_6\)  [2]} and giant magnetoresistance in Mn\(_2\) FeReO\(_6\)  [3]}. Despite that, the use of 5\(d\)  Ir ion in DP compounds have received less attention for many years. But recently, the discussion concerning the existence of excitonic magnetism in the anticipated nonmagnetic \(j\)  = 0 ground state of 5\(d^4\)  Ir\(^{5+}\)  ions in Sr\(_{2}\) YIrO\(_{6}\) 6 and Ba\(_{2}\) YIrO\(_{6}\)  have put Ir-based systems in the spotlight [4]}, [5]}, [6]}.
